Hi all:
I'd like to extend Sage's partial fraction decomposition function in
the QuotientField class to a function that works on quotients of
*multivariate* polynomials. To this end, i've found it convenient to
store a rational expression $F = P/(Q_1^{e_1} \cdots Q_m^{e_m})$ as a
Python list of the form [P,[Q_1,e_1],...,[Q_m,e_m]], where
$Q_1,\ldots,Q_m$ are the irreducible factors of $F$'s denominator.
Let's call these special kinds of lists 'widgets'. I have several
auxiliary functions that manipulate widgets.
Code design questions for you. Should i make a new class for widgets,
and if so, where in the Sage tree of modules should i put this class?
If not, where do i put the auxiliary functions that manipulate
widgets?
Thanks for your attention.
Alex
